Francis Dojun Cook in Denkoroku. The record of transmitting the light (Master Keizan) reviews circumstances with Buddhist masters and disciples.
Ungan Donjo (780 – 841) and his disciple Tozan are associated with silence, which can answer all questions by representing the empty. In a dialogue, the disciple asks: “If after your death someone asks me to draw a portrait what should I say?”, and Ungan said “Just say ‘This is like this’ ”.
It´s necessary to define a memory (idea, emotion) and represent it through forms to design a portrait. What was it? Who was he?
A portrait as the empty is always in the perspective of the vision, in that silence where all answers are found without saying a thing.
